TRACK FOR DOOR-HANGERS.

Specification of Letters Patent.

Patented Aug. 1s, 190s.

Original application led March 4, 1907, Serial No. 360,344. Divided andthis application filed March 2, 1908. Serial No. 418,639.

To all whom it may concern:

Be it known that I, SAMUEL W. BEEsoN, a citizen of the United States,residing at Buffalo, in the county of Erie and State of New York, haveinvented a new and useful Improvement in Tracks for Door-Hangers, of

which the following is a specification.

This invention relates to a track which is more particularly designedfor supporting door hangers of boX freight cars, but the same may alsobe used for other purposes.

The object of this invention is to produce a track for this purposewhich is simple and durable in construction, which will reliably supportthe hanger and the door suspended by the same, which can be produced andmaintained at comparatively small cost and which is not liable to becomederanged and rendered inoperative by the jarring or straining of thecar.

This application is a subdivision of an application for atent filed bymyself March 4, 1907, Serial o. 360,344, and patented-April8,1908,N0.s33,775.

In the accompanying drawings: Figure l is a fragmentary perspective viewof a box freight car having its door suspended from my im roved track.Fig. 2 is a fragmentary vertica transverse section taken in line 2 2,Fig. 3. Fig. 3 is a fragmentary longitudinal section in numbered line 33, in Fig. 2.

Similar letters of reference indicate corresponding parts throughout theseveral views.

Those parts of the car or other structure which receive my im rovedtrack are preferably constructed as ollowsz-A represents a supportingbeam secured lengthwise and horizontally on the outer side of the sideplate B by means of a plurality of horizontal bolts l) passingtransversely through these parts at intervals. On the underside of thissupporting beam the same is provided with a longitudinal groove or seatc which is semi-circular or nearly so in cross section. In this grooveis seated the upper side or half of a longitudinal tubular guide, way ortrack D which is rovided on its underside with a longitudina slot d.This tubular track or guide is iirmly secured in the groove of thesupporting beam by means of a plurality of vertical bolts e passingthrough the upper portions of the track and the su porting beam and eachbearing with the hea at its lower end against the bore or inner side ofthe track while its nut bears against the upper side of the supportingbeam and is prevented from becoming oose by means of a cotter pin, asshown in Figs. 2 and 3,or any other suitable means.

The horizontal bolts which connect the supporting beam with the plate Band the vertical bolts which connect the tubular track with thesupporting beam are preferably so dis osed that each horizontal bolt bis arranged c ose to one of the vertical bolts e, as shown, so that afirm connection is made between the beam and plate immediately at theoint where the vertical bolts connect the eam with the track, therebyreliably connecting the track with the car body and effectually securingagainst warping or displacement of the same under the jars or otherdestructive action to which the car is subjected. The suspending devicewhereby the door is slidingly supported from said tubular guide or trackconsists preferably of two hangers or shoes F. Each of these hangersconsists of an upper enlargement, head or runner f which 1s adapted toslide lengthwise in the bore of the tubular track, a reduced portion orneck g projecting downwardly from the underside of the head through theslot in the bottom of the track, and a socket h which is arranged at thelower end of said neck and in which the upper edge of the adjacentortion of the door 1s secured by means of bo ts i or otherwise. Theupper side of the head is concaved or recessed lengthwise so as to forma clearance space for avoiding interference with the heads of thevertical bolts e which are arranged in the upper part of the track.

Inasmuch as the tubular track is confined on opposite longitudinal sidesby the walls of the groove of the supporting beam the metal of the trackon opposite sides of its slot is held against spreading under thedownward pull of the hanger, thereby always retaining the guiding andsupporting devices of the door in their operative condition. The innerwall of the groove of the supporting beam is confined between thetubular track and the adjacent plate of the car body, whereby this wallis positively held against displacement. In order to also guard againstany possibility of the outer wall of said su porting beam from becomingdisplaced a plhrality of clips are'provided each of which consists of avertical body plate K secured tothe outer side of the sup- Aporting beamby one of the horizontal bolts b and a lip Z projecting inwardly fromthe lower porting beam in the manner described, the

same is held perfectly straight at all times and prevented from becomingaccidentally bent, thereby insuring a smooth surface Jfor thesupporting'shoe or hanger to run on and enabling the door to be easilyopened and closed at all times. The lower edge of the door is preventedfrom swinging outwardly away from the car body by the usual door trackbrackets m, but if these should be accildentally knocked ol, the doorwould still be prevented from swinging outwardly by engagement of theouter sides of the necks of the hangers with the stationary edge of thetubular track, thereby avoiding interference and damage by collision ofthe door with other cars or obstructions which would be liable to occurif the tubular track were not held rigidly in position.

I claim as my invention:

1. rlhe combination oi' a horizontally disposed tubular track ofcircular cross section having a longitudinal slot in its underside, witha longitudinal supporting beam provided on its underside with alongitudinal groove of semi-circular cross section in which the upper'half of said track its snugly, whereby the lower parts of the track onopposite sides of its slot are sustained against spreading under theweight of a door hanger resting thereon, means for connecting the top ofthe track with the beam, and means 'for connecting the beam with asupport.

2. The combination with an upright support and a horizontally disposedbeam having a groove in its under side, bolts connecting said beam andsupport, A of a horizontally Ydisposed tubular track having alongitudinal slot in its under side and adapted to be seated inisaidgroove, bolts connecting said track and beam, and clips each having avertical body which is secured to the outerside of said beam by one ofsaid horizontal bolts and a lip arranged on said body and `engaging withthe adjacent lower edge of said beam, substantially as set forth.
